60.00
Why is 90 degrees taken as angle of reference in trigonometry?
It is not. The angle of reference is 2*pi radians or 360 degrees.
How do I calculate angular velocity from revolutions per second?
1 revolution = 2*pi radianstherefore, k revs per second = 2*k*pi radians per second or if you still work in degrees, it is 360*k degrees per second.
